Protesil™ WO is a novel hybrid polymer created from the fusion of silk peptides and silicone. It performs as an emulsifier, especially for water-in-oil emulsions. This product makes it very easy to obtain stable emulsions with great compatibility with various kinds of oils under cold process. In finished formulations, it provides a smooth and silky after-feel as well as skin moisture without the usual oily tackiness. This product is preservative free. It is developed and manufactured in Japan by SEIWA KASEI.

Promois™ WK-Q is a cationized derivative of hydrolyzed keratin.Thanks to its cationic character, it can adsorb to the damaged part of the hair, repair very effectively and improve texture. It also has anti-static properties. Keratin is one of the structural proteins that compose the hair, the nails and the stratum corneum of the skin. It makes up 80% of human hair. About its amino acid composition, it must be noted that keratin has plenty of cystine, the amino acid that forms a bond between the helix of the protein and thus provides physical resistance to the hair structure as well as moisture. This is why it is important to supply keratin regularly through hair care products. Promois™ series is a range of peptides and derivatives obtained through hydrolysis of natural proteins. It is developed and manufactured in Japan by SEIWA KASEI.

Promois™ WS is a hydrolyzed soy protein with conditioning efficacy. Soy protein is distinct from animal proteins such as collagen and keratin in that, and it is composed of 30% glutamic acid and aspartic acid that possess particularly high moisturizing property. It also provides a smooth and pleasant texture and prevents unmanageable hair. Promois™ series is a range of peptides and derivatives obtained through hydrolysis of natural proteins. It is developed and manufactured in Japan by SEIWA KASEI.

Promois™ EU-118(IS) is an acylated derivative of hydrolyzed fish scale collagen. Because it is oil-soluble it can be formulated into waterless formulae such as hair-oil. Fish collagen is well-known for its excellent moisturizing properties that improves skin and hair softness. As such, it can make a good alternative to swine and bovine collagen if needed. This product is preservative free. Promois™ series is a range of peptides and derivatives obtained through hydrolysis of natural proteins. It is developed and manufactured in Japan by SEIWA KASEI.

Promois™ W-52QP is a powder cationized derivative of hydrolyzed collagen from swine gelatin. Thanks to its cationic character, it can adsorb to the damaged part of the hair, repair very effectively and improve texture. It also has anti-static properties. Collagen is a major component of skin protein. It plays a significant role in building up and maintaining our body. Collagen comprises approximately 1/3 of protein in mammals. Its distinguishing characteristic is that it is the only protein to contain both hydroxyproline and hydroxylysine, two amino acids that bring high moisture to both skin and hair. This product is powder type. Promois™ series is a range of peptides and derivatives obtained through hydrolysis of natural proteins. It is developed and manufactured in Japan by SEIWA KASEI.

Promois™ WK-GBF is a hydrolyzed keratin of high molecular weight. Keratin is one of the structural proteins composing the stratum corneum, hair, and nails. It makes up 80% of human hair. About its amino acid composition, it must be noted that keratin has plenty of cystine, the amino acid that forms a bond between the helix of the protein and thus provides physical resistance to the hair structure as well as moisture. This is why it is important to supply keratin regularly through hair care products. Promois™ series is a range of peptides and derivatives obtained through hydrolysis of natural proteins. There are also products with different preservatives. It is developed and manufactured in Japan by SEIWA KASEI.

Promois™ W-52U is hydrolyzed collagen from fish scale with conditioning efficacy. Fish collagen is well-known for its excellent moisturizing properties that improves skin and hair softness. As such, it can make a good alternative to swine and bovine collagen if needed. Promois™ series is a range of peptides and derivatives obtained through hydrolysis of natural proteins. It is developed and manufactured in Japan by SEIWA KASEI.

Promois™ W-42 is hydrolyzed collagen from swine gelatin with conditioning efficacy. Collagen is a major component of skin protein. It plays a significant role in building up and maintaining our body. Collagen comprises approximately 1/3 of protein in mammals. Its distinguishing characteristic is that it is the only protein to contain both hydroxyproline and hydroxylysine, two amino acids that bring high moisture to both skin and hair. Promois™ series is a range of peptides and derivatives obtained through hydrolysis of natural proteins. It is developed and manufactured in Japan by SEIWA KASEI.

Promois™ EF-118AMP is an acylated derivative of hydrolyzed silk protein that is alcohol soluble. Silk protein is formed of two proteins: fibroin and sericin. Fibroin has a unique amino acid composition. It is rich in glycine, alanine and serine which have small molecular weight and simple chemical structure. This composition is known to form a sheet structure to which is associated the comfortable touch of silk. The amino acids of sericin have many hydroxyl groups which provides uncomparable moisturizing effect. This product is preservative free. Promois™ series is a range of peptides and derivatives obtained through hydrolysis of natural proteins. It is developed and manufactured in Japan by SEIWA KASEI.

Promois™ ESCP is an acylated derivative of hydrolyzed soy protein. Soy protein is distinct from animal proteins such as collagen and keratin in that it is composed of 30% glutamic acid and aspartic acid that possess particularly high moisturizing property. It also provides a smooth and pleasant texture and prevents unmanageable hair. Promois™ series is a range of peptides and derivatives obtained through hydrolysis of natural proteins.
